Original application filed October 2, 1922, Serial No. 591,778. Dividedand this application filed. October 17,

mar. Serial No. 744,149.

This application is a division of my application Serial No. 591,778,filed October 2, 1922.

This invention relates to valves, and while the invention may be appliedto valves used for various purposes, it is especially useful when usedin connection with valves such as are used on air hose for fillingautomobile tires with compressed air. These valves are carried on theend of a hose and after disconnecting them from the inflating nipple ofthe tire they are usually permitted to fall, or are thrown down upon theground or upon a cement floor, as the case may be. The valve is usuallyoperated by a lever, and when subjected to such rough usage the leversare frequently broken; such breakage tends to occur usually at the pointof connection of the lever with the valve body. The general object ofthis invention is to provide simple means for operating such a valve,which is so constructed as to prevent injury to it or to its connectionwith the valve body ifthe valve is thrown around carelessly, assuggested above; more particularly, one of the objects of my inventionis to provide a valve and lever of such a construction as will preventlateral movement of the lever and thereby prevent breaking off the lugsby means of which the lever is connected to the valve body.

Further objects of the invention will appear hereinafter.

The invention consists in the novel parts and combination ofv parts tobe described hereinafter, all of which contribute to produce asubstantially indestructible valve.

A preferred embodiment of this invention is described in the followingspecification, while the broad scope of the invention is pointed out inthe appended claims.

In the drawing:

Fig. 1 is a vertical section through a valve embodying my invention.

Fig. 2 is an end elevation of the valve shown in Fig. 1 and showingthe'same as viewed from the left end.

Fig. 3 is an end elevation showing the other end of the valve.

Fig. 1 is a plan of the valve.

My invention is capable of attachment to a valve of any constructionwhich can be operated by a lever. In the present instance I havedescribed my invention as applied to a valve of the constructionillustrated in the drawing and in which 1 represents a valve bodyprovided with a check valve 2 having a stem 3 projecting from the valvebody and normally held on its seat by a light spring 4.

By shoving in on the stem 3 the valve 2 can be held off its seat, andwhen this occurs compressed aid can flow from the inlet opening 5through ports 6 and 7 so as to pass through the outlet opening 8 whichis connected to a small hose which connects with the inflating nipple ofthe tire.

The inlet opening 5 is provided with means such as screw threads forattaching the same to the air hose, and if desired similar threads maybe provided at the outer opening 8 for connecting it with the short hoseconnection which connects to the inflat ing nipple.

The valve illustrated is also provided with a barrel 9 within whichthere is mounted a guage 10 which is forced outwardly by the airpressure when the valve is open; for this purpose air is admitted to theinner end of the gauge 10 through a suitable port 11.

In applying my invention to such a valve, I provide means such as thelever 12 for engaging the stem 3 to force the same inwardly and thislever is preferably connected by a suitable pivot means to the valvebody. This lever is a simple lever and is devoid of any additionalweight. In the present instance this connection involves the use of apin 13 which is mounted between two lugs 14 which project from the sideof the barrel 9. The lever fits into the space between these lugs. I

I provide means for engaging and guiding the lever 12 at a point removedfrom the pivot means. The pivot pin 18 and this guiding means operatesto prevent lateral movement of the lever; at the same time I prefer toconstruct this guiding means so that it limits the movement of the leveron its pivot. In order to accomplish this I provide the body 1 of thevalve with a projection or lug 15 which is received in a guide socket 16me tail 1? which extends downwardly from the end of the lever 12, thatis to say, it projects at right angles to the body of the lever andprojects down along the side of the valve. The side faces 18 of theopening or slot 16 engage the side I faces of this lug 15. The lngtherefore op era-tes to prevent lateral movement of the lever end, butit does not prevent vup and down movement of the lever in controllingthe valve. However, the end of the tall 17 is in the form of a cross-bar19 which lies directly under the lug 15 and thus limits the outwardmovement of the lever. Above the leg 15 a sulfioien gap 20 is provided(see Figure 1) which permits the downward movement of the lever whichopens the valve.

lVith :a valve body and lever constructed as described, it will beevident that any blow or force tending to move the lever laterlally willbe resisted by the 15 and this will prevent breaking the lever or thelugs 14; hence this valve may be thrown about carelessly Without injuryto the valve lever.

lt is understood that the embodiment ot the invention described hereinis only one of the many embodiment-s this invention may take, and I donot wish to be limited in the practice of the invention, nor in theclaims, to the particular embodiment set forth. 7

ll hat I claim is 2- r V 1. In a valve to be attached to the end of ahose, the combination of a body with means for attaching the same to ahose and to the inflating nipple of a tire, a lever having a pivotattaching the same to the body for opening the valve,

said body having a projection tor engagin' and positively guiding thelever at a point removed from thepivot, operating to prevent lateralmove 'ment of the lever and relieve the pivot of lateral strain, saidlever having means tor engaging the projection to limit the swing- 'in-gmovement of the lever on its pivot.

2. In a valve to be attached to the end of a hose, the combination of abody with means for attaching the same to a hose and to the infiatingnipple ol a tire, a lever having a pivot for attaching the same to thebody, :a valve within the hotly having a stem engaged by the lever toenable the valve to be opened by pressing the lever, said body having alug projecting theretrom, said lever having a socket receiving the saidlug with he sides of the socket engaging the sides 0tthe lug andoperating to prevent lateral movement of the lever, thereby relievingthe pivot of lateral rs'trratns, the :E-lllfil oi the :soolretcooperating with the lug to limit the upward movement of the lever.

3. 'ln a valve to be atta-el-ied to the end of a hose, the combinationol a body with means for attaching the same to the hose and to theinflating nipple ot a tire, a lever having pivot-means for attaching thesame to the body 501' o 'ier-ling the valve, laving an extension at itsouter end projecting si-ibstantially at right at-igl'es to the body orthe lever and protecting "along the'side ol? the body, said hody havingmeans f-or engaging and positively guiding the lever at a point on thelast named side :and removed from the pivot-means, operating to preventlateral movement ol' the lever :and thereby relieving the saidpivot-means oit lateral strains.

4. In a valve to be attached to the end of a hose, the combination of abody with means for attaohing the same to the hose and to the inflatingnipple ot a tire, :a lever having "pi -v ot-rneans for attaching thesame to the body for opening the valve, and having an evtmision at itsouter end projecting substantially at right angles to the body of thelever and projecting along the side of the body, and having :a slot i nsaid extension, said hotly having :a lug projecting into thesocketlimiting the outward movement of the lever and .coorp'eratiaigwith the socket to prevent lateral movement oat the lever, and therebyrelieving the pivot :of lateral strains.
